Accelerating Medicines Partnership® Schizophrenia (AMP® SCZ): Rationale and Study Design of the Largest Global Prospective Cohort Study of Clinical High Risk for Psychosis.

This article describes the rationale, aims, and methodology of the Accelerating Medicines Partnership® Schizophrenia (AMP® SCZ). This is the largest international collaboration to date that will develop algorithms to predict trajectories and outcomes of individuals at clinical high risk (CHR) for psychosis and to advance the development and use of novel pharmacological interventions for CHR individuals. We present a description of the participating research networks and the data processing analysis and coordination center, their processes for data harmonization across 43 sites from 13 participating countries (recruitment across North America, Australia, Europe, Asia, and South America), data flow and quality assessment processes, data analyses, and the transfer of data to the National Institute of Mental Health (NIMH) Data Archive (NDA) for use by the research community. In an expected sample of approximately 2000 CHR individuals and 640 matched healthy controls, AMP SCZ will collect clinical, environmental, and cognitive data along with multimodal biomarkers, including neuroimaging, electrophysiology, fluid biospecimens, speech and facial expression samples, novel measures derived from digital health technologies including smartphone-based daily surveys, and passive sensing as well as actigraphy. The study will investigate a range of clinical outcomes over a 2-year period, including transition to psychosis, remission or persistence of CHR status, attenuated positive symptoms, persistent negative symptoms, mood and anxiety symptoms, and psychosocial functioning. The global reach of AMP SCZ and its harmonized innovative methods promise to catalyze the development of new treatments to address critical unmet clinical and public health needs in CHR individuals.

Disfunción sexual en mujeres con lupus eritematoso sistémico / Sexual dysfunction in women with systemic lupus erythematosus

Introducción: la disfunción sexual (DS) es la alteración en una o varias de las fases de la actividad sexual. Puede culminar en frustración, dolor y disminución de la frecuencia de las relaciones sexuales. Objetivos: determinar la frecuencia de DS y analizar los factores asociados en pacientes con lupus eritematoso sistémico (LES). Materiales y métodos: se realizó un estudio de corte transversal. Se incluyeron pacientes femeninas con LES, entre 18 y 50 años, se excluyeron aquellas con síndrome de Sjögren, menopausia, depresión severa y analfabetas. Se evaluaron variables demográficas y de la enfermedad. Se aplicó la escala Depression Anxiety Stress Scale (DASS-21) y el Índice de Función Sexual Femenina (Female Sexual Function Index, FSFI). Se comparó con un grupo control sano. Resultados: se evaluaron 60 mujeres con LES y 63 controles. La prevalencia de DS en LES fue de 71,7% y hubo diferencias significativas en todos los dominios de la función sexual. El score total del FSFI en pacientes con LES fue menor al comparar con los controles. Según la escala DASS-21, estrés, ansiedad y depresión se observaron en al menos la mitad de mujeres lúpicas, sin embargo, no se encontró asociación entre estas variables y DS. Conclusiones: la prevalencia de DS en pacientes con LES fue elevada. Depresión, ansiedad y estrés no fueron determinantes en la presencia de DS.

Introduction: sexual dysfunction is the alteration in one or several phases of sexual activity. It can culminate in frustration, pain and a decrease in the frequency of sexual intercourse. Objectives: determine the frequency of sexual dysfunction and analyze associated factors in patients with SLE. Materials and methods: a descriptive cross-sectional study was conducted. We included patients with SLE, between 18 and 50 years of age, Secondary Sjogren's syndrome, menopause, severe depression and illiterate patients were excluded. Demographic and disease-related variables were studied. The Depression Anxiety Stress Scale (DASS-21), and the Female Sexual Function Index (FSFI) were applied. Results: sixty women with SLE and 63 controls were evaluated. The prevalence of SD in SLE was 71.7% and there were significant differences in all domains of sexual function. The total FSFI score in patients with SLE was lower when compared to controls. According to the DASS-21 scale, stress, anxiety and depression were observed in at least half of lupus women, however no association was found between these variables and SD. Conclusions: the prevalence of SD in patients with SLE was high. Depression, Anxiety, and Stress were not determinants in the presence of SD.

Cannabinoides sintéticos / No disponible

Las nuevas sustancias psicoactivas, de las que se describen sus características y clasificación, enmarcan el fenómeno de los cannabinoides sintéticos, que ocupan un lugar central entre ellas. De los cannabinoides sintéticos se revisa su mecanismo de acción, clasificación, efectos y datos de consumo en España. Se concluye que este mercado, con gran número de sustancias, es cambiante y que todavía es limitado el conocimiento científico sobre sus datos epidemiológicos, su farmacocinética, los patrones de distribución en tejidos y órganos, sus interacciones y efectos clínicos. Todo ello hace necesaria la investigación para discernir sobre estas lagunas de conocimiento

The new psychoactive substances, of which its characteristics and classification are introduced, contextualize the phenomenon of synthetic cannabinoids, central among them. The mechanism of action, classification, effects and use data from Spain of synthetic cannabinoids are reviewed. It is concluded that this market, with a large number of substances, is changing and that there is still a limited scientific knowledge about epidemiological data, pharmacokinetics, distribution patterns in tissues and organs, their interactions and clinical effects. More research is needed to discern these knowledge gaps
